My issue

include <bits/stdc++.h>
using namespace std;

void solve() {
int N;
cin >> N;

vector<int> arr(N);
for (int i = 0; i < N; i++) {
    cin >> arr[i];
}
cout<<N;


for(auto &x : arr)cout<<x<<" ";

}

int main() {
ios::sync_with_stdio(0);
cin.tie(0);

int T;
cin >> T;
while (T--) {
    solve();
}

return 0;

}
